As you know the
custom url protocol is a feature that allow us to make a communication between a web page and our application. For example, Y! Messenger uses this protocol when you want to send a pm to another person through a web page:
<a href="ymsgr:sendim?YahooID">Click to send pm</a>
Now, the question is how can I monitor(hook) all
custom url protocol messages in the windows? Is it possible to catch them?
